FIELD OF THE INVENTION

The present invention relates to a system and method of providing a content discovery platform for optimizing social network engagements.

BACKGROUND OF THE INVENTION

Social networks have become an integral part of peoples' lives. Millions of people use social networks every day to communicate about a variety of topics, publish opinions and share information. Marketing experts have long recognized that an effective marketing strategy must include a presence on social networks. For example, many corporate users, particularly those that sell consumer products, communicate through Twitter as well corporate pages on LinkedIn and Facebook to reach social network users (their audience). It has been found, however, that social network presence alone is not adequate to maintain and more importantly, increase brand awareness, company influence, number of followers and ultimately sales of products or services. A user must actively engage and create a relationship with social network users (i.e., user's audience) directly in order to be effective. User engagement may include tweeting and retweeting and posting articles and comments on various topics for social network users (i.e., user's audience). High social media influence (called influencers) is desired but difficult to achieve because content relevant to the topics associated with the user (and of interest to the user's audience) is difficult to identify with current methods and systems.

It would be therefore advantageous to provide methods and systems to improve upon the current methods and systems.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present disclosure are described herein with reference to the drawing figures.

FIG. 1 depicts a block diagram illustrating an example system 100 in which a content discovery platform for optimizing social network engagements (i.e., interactions from a user's audience on social networks) operates.

In this embodiment, system 100 includes a central system 102 that communicates with social networks 104, and content sources 106, 108 via network 110. Network 110 is the Internet, but it may be other communication networks such as a local area network (LAN) or both the Internet and LAN as known to those skilled in the art. System 100 also includes one or more clients 112 that enable users to communicate with social networks 104, content sources 106, 108 and central system 102 via network 110 by cable, ISDN, WIFI or wireless carrier networks as known to those skilled in the art. (Data and information are used interchangeably in this disclosure unless otherwise noted.)

Central system 102 incorporates content discovery platform 200 (described below) for optimizing social network engagements (i.e., interactions with a user's audience on social networks 104). Central system 102 includes one or more servers that may be connected together through a network such as a local area network (LAN) as known to those skilled in the art. The one or more servers may include a web server as known to those skilled in the art. Each server includes several internal components (e.g., processor, memory, drives, etc.), databases, operating system, software modules and applications (e.g., browser) as known to those skilled in the art. An example server is described below with respect to FIG. 9.

Social networks 104, as known to those skilled in the art, are typically web-based systems that allow users to create a profile, post content, connect to other users, engage with content and create a list of users with whom to share such content (e.g., social media data). The content may be photos, videos, articles or any other information and/or links linking to such content. Social networks 104 typically provide a means for users to interact over the Internet such as email and/or instant messaging. Examples of social networks 104 include LinkedIn, Twitter, Facebook, Google+, Instagram, Pinterest and Tumblr (to name a few). These web-based systems include one or more servers that may include a web server. Each server includes several internal components (e.g., processor, memory, drives, etc.), databases, operating system, software modules and applications (e.g., browser) as known to those skilled in the art. An example server is described below with respect to FIG. 9.

Content sources 106 is a system of one or more servers that comprise any number of news or other sources of information that provide RSS feeds to enable users to access such information. Examples of content sources include ABC, Bloomberg, Business Insider, Fast Company (to name a few). Each of theses sources provide RSS feeds to enable users to access information on its platform typically done by newsreaders. Content sources 108 is also a system of one or more servers that comprise any number of events, articles, PDFs, videos, photos or other (together “articles”) that users may access via a URL (uniform resource identifier) posted on social networks 104 that link to such articles as known to those skilled in the art. The one or more servers may include a web server as known to those skilled in the art. Each server includes several internal components (e.g., processor, memory, drives, etc.), operating system, databases, software modules and applications (e.g., browser) as known to those skilled in the art. An example server is described below with respect to FIG. 9.

Each client 112 includes a personal computer and a monitor. The personal computer includes several internal components (e.g., processor, memory, drives, etc.), operating system, databases, software modules and applications (e.g., browser) as known to those skilled in the art. Clients 112, however, could be smartphones, cellular telephones, tablets, PDAs, or other devices equipped with industry standard (e.g., HTML, HTTP etc.) browsers or any other application having wired (e.g., Ethernet) or wireless access (e.g., cellular, Bluetooth, IEEE 802.11b etc.) via networking (e.g., TCP/IP) to nearby and/or remote computers, peripherals, and appliances, etc. TCP/IP (transfer control protocol/Internet protocol) is the most common means of communication today between clients or between clients and central system 102 or other systems (i.e., one or more servers), each client having an internal TCP/IP/hardware protocol stack, where the “hardware” portion of the protocol stack could be Ethernet, Token Ring, Bluetooth, IEEE 802.IIb, or whatever software protocol is needed to facilitate the transfer of IP packets over a local area network. Each client 112 may access the Internet directly or through a system 114 (shown in dotted lines) of one or more servers that communicates with Internet as known to those skilled in the art. These users may be an independent person, a representative of a corporate or government entity or any other person accessing information from central system 102, social networks 106, and/or content sources 106, 108.

As shown in FIG. 2, central system 102 incorporates content discovery platform 200 for optimizing content discovery through social networks 104. In brief, content discovery platform 200 is a framework that enables a user to discover high quality web content collected from various sources that is most relevant to a set of topics associated with the user. Content discovery platform 200 relies on users connections on social networks 104 to understand, among other things, topics of interest and expertise related to cohorts of users and other demographics information. Content discovery platform 200 then performs content discovery, collection and ranking on URLs and RSS feeds using extraction and machine learned scoring models.

In a bit more detail, content discovery platform 200 collects social media data, RSS feeds and articles, creates URL summarization documents from the collected data, creates features for capturing different aspect of an article's relevance using machine learning and trains models on subsets of articles to determine the weights for each feature. Models may be trained with different objectives. For example, the models may be trained to optimize for different social network user interactions such as favorites, likes, clicks, user shares, audience reactions etc. Content discovery platform 200 then scores the URL summarization documents (URLs) using the trained models and the top articles are retrieved in order of score (rank) and presented to the user. The user determines the actual number of articles presented. Content discovery platform 200 is described in more detail below.

Content discovery platform 200 comprises one or more software applications, modules, computer instruction set and/or databases including (1), discovery and collection modules 202, 204, (2) summarization processing module 206, (3) relevant scoring feature 208, (4) model selection engine 210 and serving module 212. Content discovery platform 200 further includes collector database 214, Klout database 216 and model database 218. These modules/databases are described in detail below.

Discovery and collection modules 202, 204 are the software applications or modules (or set of computer instructions) that provide the infrastructure to discover and collect highly relevant content from sources such as social media (e.g., Twitter streams), RSS feeds and news articles. Discovery and collection modules 202, 204 select URL content from recent historical social media sharing. The collected content typically includes millions of articles per day. A URL list is generated by considering the number of shares, number of reactions and Klout score of people that shared the URL within an arbitrary time frame (15 minutes in near real time to 1 day in batch processing case). Only the most important URLs are fetched—the ones that were shared by highly influential people or the ones that created a lot of buzz. RSS content sources are selected by a combination of automated inference of social curation and manual curation. Specifically, an RSS list is a combination of a manually curated list of sources and automatically generated list based on URLs fetched in the past. The automatically generated list extracts RSS source links from (meta tags of ‘application/rss+xml’ that is embedded in) the HTML page. In this way, most links can be associated with the RSS feed from which they originated. This combined with the measure of original HTML page (content of URL) popularity within social networks allows content discovery platform 200 to generate an RSS feed scored list, where score is good predictor of how popular the links within RSS feed will be. (Stated differently, discovery of URL sources is based on a scoring system that incorporates the relevance and popularity of the articles at the current time.)

Summarization processing module 206 is the software application or module (or set of computer instructions) that summarizes the collected URLs (articles) and other related data into documents of normalized format using a combination of multiple text analysis techniques. Specifically, summarization is a process of parsing HTML pages to extract information of interest (fields) on the page. Keywords and topics, for example, are derived for each article based on text classification and natural language processing (NLP) analysis.

Feature generation module 208 is the software application or module (or set of computer instructions) that extracts features from a summarization document relating to an article including collection statistics (e.g., projected trends), timeliness, publisher of the article (e.g., authors expertise), and users interacting on social networks 104 with the article (e.g., number of shares). Feature generation module 208 leverages Klout data from topical and overall reputation. (As known by those skilled in the art, Klout data is derived using a tool for measuring social influence as known to those skilled in the art. For a given social network user, Klout data includes a Klout score, per network score, topical interest scores, topical expertise scores, keyword interest scores and keyword expertise scores.) The relevance of articles to topics is determined by applying a pre-determined model to these extracted features. The applied model is created offline using past actions of users. The score documents are ranked and retrieved based on their relevance. This is described below.

Model selection module 210 is the software application or module (or set of computer instructions) that enables a user or admin to select different relevance modules to be applied to a set of generated features for calculating ranking values for URLs. Module 210 also allows flexibility in terms of multivariate testing of subsets of extracted features or rules to be applied while presenting articles to users. This framework is used to experiment and gather data points for improving relevance machine learned models, in order to produce an optimized content for users.

Serving module 212 is the software application or module (or set of computer instructions) that provides multiple serving infrastructures. It may include a batch pipeline that performs feature generation (above) and relevance scoring of URLs in bulk. Serving module 212 also may use Elasticsearch where summarized documents are indexed and surfaced with low latency. Serving module 212 is also involved in serving (presenting) the top URLs to a user.

Collector database 214 is a database, that stores collectors used to collect social media data from social networks 104. Klout database 216 is a database that stores Klout data generated using the Klout social influence tool described above. Model database 218 is a database that stores models that are used to incorporate the importance of features (described below) and calculates a score based on those features. URL summarization database 220 is a database that stores URL summarization documents (described below). Index database 222 is a database that stores an index of URL summarization documents. Social media database 224 is a database that stores social media data collected from social networks 104 as described in this disclosure. User interaction log database 226 is a database of a log of user interactions. RSS feed database 228 is a database of RSS feeds. Databases 214-228 are databases known to those skilled in the art. However, those skilled in the art know that any data storage or strategy other than a database be used for storing the data disclosed in this disclosure. In addition, some databases may be available publicly via an application interface (API) (e.g., Klout database).

Execution proceeds to step 310 wherein summarization documents for the ranked URLs are generated using summarization processing module 206. At this step, HTML pages are content parsed to extract information of interest on the pages. Direct and indirect fields of extraction are shown in FIG. 5. Specifically, certain fields are extracted directly such as title, description, article text, publication time, processing time, author information etc. Other fields are directly derived from the web page but require additional processing to extract the best match. These fields include (1) publication timestamp, through parsing timestamps associate with the web page and (2) image URLs ranked by the image quality estimated from the byte content. Indirectly derived fields include the language of the article, keywords of the topics extracted using proprietary text analysis techniques (e.g., parsing HTML, term frequency-inverse document frequency (TF-IDF) weighted bag of words, or the keyword extraction techniques disclosed in U.S. application Ser. No. 14/627,151, filed Feb. 20, 2015, entitled “Domain Generic Large Scale Topic Expertise and Interest Mining Across Multiple Online Social Networks,” which is incorporated by reference herein), and blacklisted domain identification matched against a list of blacklisted domains. An example of a summarization document appears in the rear of this disclosure.

FIG. 3 depicts example method steps for implementing the discovery, collection, and summarization modules shown in FIG. 2.

In particular, execution begins at step 300 wherein social media data is collected by collection module 204 using a set of collectors from collector database 214. The data collected is stored in social media database 224. The social media data includes all data from registered users on social networks 104. For example, the data will include all Twitter public data (via GNIP or other streams). The data will also include comments and posts including URLs and all data on other social networks 104 (e.g., Facebook, Google-+, LinkedIn) including any other data that relates to those URLs (for all “connected” registered users). Connected users may be a friend or other connections or followers on social networks 104 that has some connected to the data (content) as known to those skilled in the art. For example, the data will include a specific user (author of post), actor (person that engaged), action (like, favorite, tweet, comment, share), message and URL. The data is typically collected from about 300 million users a month, but different amounts may be collected at different intervals as known to those skilled in the art.

Execution proceeds to step 302 wherein the social media data is processed to aggregate the data associated with each URL. Specifically, the data is aggregated by the number of users, actors and actions with respect to the URL as follows:

-   -   Example URL=({user}, {actor}, {action} . . . )         (The URL being a set of interactions.)

Aggregation on a URL may be accomplished using Hive or another third party tool known to those skilled in the art.

Execution proceeds to step 304 wherein a social importance score is computed for each URL as a function of a Klout score as identified by a Klout ID for a user and aggregated data. Social importance score is an estimate of engagement (i.e., interaction of a user's audience) of an article on social networks. Specially, the social important score (F) computed as follows:

${F^{URL}({url})} = {\sum\limits_{{i❘{t \in T}},{url}}{{w(e)}*\left( {{\alpha*{g\left( k^{u} \right)}} + {\beta*{g\left( k^{a} \right)}}} \right)}}$ where the parameters identified above are defined as follows:

-   -   Interaction tuple: i=(t, url, u, k^(u), a, k^(a), e)     -   i: interaction tuple     -   t: timestamp of when interaction occurred     -   url: URL around which interaction occurred     -   u: user that created original post on social network (e.g.,         @ubunto)     -   k^(u): Klout information of user u k=(score, topics, keywords,         demographic_info). As shown above, this includes Klout score,         demographic information, and various topical/keywords sets         derived for a user and stored in Klout (knowledge) database 216.     -   a: actor or user (e.g., @santori follower of @smith) that         ‘acted’ on original post via social network event e (like,         comment, re-tweet, . . . etc.)     -   k^(a): Klout information of actor “a” (score, . . . etc.)     -   e: event type of interaction (like, comment, favorite, re-tweet,         . . . etc.)     -   T=[t_(start), t_(end)]: time window in which a given URL is         scored.     -   α: original user importance weight (scalar)     -   β; actor importance weight (scalar)     -   w: event weighting function to allow different events to be         weighted differently (Twitter comment vs. Facebook comment etc.         . . . )     -   g: user weighting function. Given user's information, and in         particular, Klout information, weight of given user can be         derived. (The user can have different importance.)

(The social importance score is to weight different interaction events with different values.) An example of one possible simplified formula can be: F ^(URL)(url)=Σ_(i|tϵT,url)1.0*(0.1*k ^(a)·score+0.9*k ^(u)·score) where g(k)=k·score and k·score is the Klout score. In the computation of social importance score, an alternative for a Klout score is may be used for determining the weight value g(k). For example, an equal (constant) weight value may be assigned for every user (i.e., same influence). For example, g(k)=1.0 (weight value of 1), then URL scoring function becomes a frequency count of a URL across social networks 104.

Execution then proceeds to step 306 wherein the URLs are ranked (sort) by the social importance score. At step 308, a designated number (M) of the top URLs by ranked score are fetched (collected). (M) may be selected as an number as known to those skilled in the art, but system requirements/constraints as well as diminishing returns may factor into the value for (M). For example, 300,000 URLs may be selected, but as indicated, any number may be selected as known to those skilled in the art. These fetched URLs are collected and queued in a distributed manner for efficient processing.

Execution proceeds to step 310 wherein summarization documents for the ranked URLs are generated using summarization processing module 206. At this step, HTML pages are content parsed to extract information of interest on the pages. Direct and indirect fields of extraction are shown in FIG. 5. Specifically, certain fields are extracted directly such as title, description, article text, publication time, processing time, author information etc. Other fields are directly derived from the web page but require additional processing to extract the best match. These fields include (1) publication timestamp, through parsing timestamps associate with the web page and (2) image URLs ranked by the image quality estimated from the byte content. Indirectly derived fields include the language of the article, keywords of the topics extracted using proprietary text analysis techniques (e.g., parsing HTML, term frequency-inverse document frequency (TF-IDF) weighted bag of words, or the keyword extraction techniques disclosed in U.S. application Ser. No. 14/627,151, filed Feb. 20, 2015, entitled “Domain Generic Large Scale Topic Expertise and Interest Mining Across Multiple Online Social Networks,” which is incorporated by reference here), and blacklisted domain identification matched against a list of blacklisted domains. An example of a summarization document appears in the rear of this disclosure.

As part of the summarization processing, certain properties are derived from the articles that relates to aspects or characteristics of the articles to enable subsequent processing by the feature generation module 208 (as described below). Specifically, relevant scoring is performed to score (generate values for) certain aspects or characteristics of the articles to assess the relevancy of such aspects. The properties or scores are set forth in each summarization document for these aspects. The aspects or characteristics of relevance that are considered during scoring are (1) topic and keyword relevant to the user, (2) the publisher diversity, (3) timeliness of the articles, and (4) social signals (trending). This is described below.

(1) Topic and Keyword Relevance to the User.

Topics and keywords are first extracted for each article using text analysis (TF-IDF, Named Entity Extraction, or Dictionary Based Phrase Extraction) known to those skilled in the art. Keywords are mapped to topics by simple one to many mapping using manually curated list, or mappings derived using machine learning techniques like Naïve Bayes. This step analyzes text from the title, description, meta text, article text, topics and keywords assigned to the author of the article and topics and keywords assigned to users who shared the article. Topic and keywords derived from the above are assigned a score that signifies how closely the article is related to the topic or keyword. The keywords and topics are derived using a keyword dictionary and topic ontology, respectively. This score may be derived from techniques such as term frequency, inverse document frequency etc. as known to those skilled in the art. Topic and keyword derivation and scoring may be accomplished by the techniques disclosed in U.S. application Ser. No. 14/627,151, filed Feb. 20, 2015, entitled “Domain Generic Large Scale Topic Expertise and Interest Mining Across Multiple Online Social Networks,” which is incorporated by reference herein. Different topic and keyword sets may be applied to the user for whom articles are fetched. Some user sets include topics and keywords of user's interested, topics and keywords of the user's expertise, topics and keywords of interest to the user's audience (per social network, or combined), self selected topics and keywords and trending topics and keywords. For a given topic and keyword set chosen for a user, the articles which have a high score for the topics and keywords are ranked and retrieved.

(2) Publisher Diversity.

Publisher diversity: for the same topic, articles from a wide variety of publishers and sources are extracted and surfaced (presented) to the user. Publishers are ranked by the quality of the articles published, which is determined by the number of shares and reactions that articles from the publisher receive. Features (as described below) are created to represent the publisher rank for each article, and articles with higher publisher ranks are given higher preference.

Topic and Keyword diversity: A topic or keyword set for a user typically contains multiple topics and keywords for which articles must be extracted and surfaced. However, the number of articles for popular topics such as sports, politics and entertainment are typically a lot larger than those for niche topics such as skydiving and quantum physics. In order to ensure that in the final list of articles all topics are fairly represented, the features (as described below), and thereby scores, associated with the articles are normalized within the scope of each topic. This makes the scores comparable across topics, and creates topic diversity when the retrieved article list is ranked by scores.

(3) Timeliness.

Article Recency: A publication timestamp of an article is derived for subsequent use. Features (described below) are created to capture the recency of content, which are derived from that publication timestamp. Articles that are more recent are given a higher weight than older articles, since fresh content provides greater relevancy to the user compared to older content.

Topical Time Decay Factors: articles are created with differing frequencies for different topics. For example, a topic such as music may have thousands of articles generated daily, whereas a topic such as spearfishing may have only one article created per week. In such a situation, considering only the publication timestamp will lead to the suppression of niche topics by the wider topics. Therefore, the time-relevance of topics should be taken into account while scoring articles. Accordingly, topical decay factors are used for articles on a given topic. A decay factor is applied to each article based on its topical lifetime (measure how quickly new articles are being generated). This is done via the following steps:

1. Calculate half life for each topic, where the decaying quantity is the number of posts per topic. The mean post lifetime:

$\begin{matrix} {\begin{matrix} {{\left. {meanPostLifetime} \right.\sim = {{average}{\mspace{11mu}\;}{time}\mspace{14mu}{between}\mspace{14mu}{posts}}}\;} \\ {\left( {{in}\mspace{14mu}{seconds}} \right)\mspace{14mu}} \\ {= {n\mspace{14mu}{days}\text{/}{total}{\mspace{11mu}\;}{posts}\mspace{14mu}{created}}} \\ {{for}\mspace{14mu}{topic}{\mspace{11mu}\;}{in}\mspace{14mu} n\mspace{14mu}{days}} \end{matrix}{{{tHalf}\mspace{14mu}({topic})} = {{meanPostLifetime}*\ln}}} & (2) \end{matrix}$

2. Calculate age of the article, as the difference between current time and the publication time, in seconds.

3. Combine topic half life with URL age to get the decay factor for the URL, where the decaying quantity is content timeliness:

tau = mean   lifetime  of   topical  content = tHalf  (topic) delta T = age_of_article $\begin{matrix} {{{decay}\mspace{14mu}{factor}} = {{scalingFactor}*{\exp\left( {{- {delta}}\; T\text{/}{tau}} \right)}}} \\ {= {{scalingFactor}*{\exp\left( {{- {age\_ of}}{\_ article}\text{/}{topic\_ half}{\_ life}} \right)}}} \end{matrix}$ Other similar features could be derived penalizing the frequency of posts within topical domain, for example using linear function rather than exponential.

This decay factor is larger for articles on topics that have higher publishing rates, and is smaller for those with lower rates. This ensures that topics are fairly represented with respect to time-relevance to the user.

(4) Social Signals.

Predicted Trends: if a certain subject begins to receive attention on social media, then it is likely that the subject will be of interest to the user. This is similar to the concept of breaking news, with the number of times an article is shared in social media approximating the attention the subject receives. Time series data is generated for articles shared on social media, where each data point represents the number of shares in a given time window. Polynomial (y=a0+a1*x+a2*x^2+ . . . ) or Logarithmic (y=c+log (x)) curve-fitting or is applied to this time series. The extrapolated curve is used to forecast the shares the article is going to receive in the near future. Features generated (described below) to forecast predicted trends are used at scoring time, and articles that are forecasted to receive more attention are prioritized over others. Features generated from predicted forecast function may be number of expected shares per unit of time

$\left( {e.g.\frac{d\; y}{d\; t}} \right),$ or expected share per unit of time growth

$\left( {e.g.\frac{d^{2}y}{d^{2}t}} \right).$ Reference is made to FIG. 6 wherein an example is shown of a measured number of actual social network engagement (i.e., interactions by a user's audience) and a predicted number of social interactions based on logarithmic function curve fit (trend corresponds to the slope of curves).

Audience Seen Likelihood: if optimization for the user's audience reactions is desired, then the number of times an article has already been shared can also be used to estimate what percentage of the user's audience may have already seen the article. Features (discussed below) are generated to represent this likelihood, and articles with higher seen likelihood values are suppressed compared to the others. This is almost an inverse measure to the feature for rewarding trending articles, and either feature may have a different weight depending on the objective for optimization.

Topics and keywords of users sharing articles: since topics and keywords are derived for users on social media, topic and keyword strengths can be identified for an article based on the topics and keywords of the users who shared the article on social media. These topic and strengths can then be later used as features to improve assignment of topics and keywords to articles, thereby improving topical relevancy while surfacing them to new users.

Thus, the data or properties described above with respect to scoring (e.g., features for topic and keyword relevance, diversity, timeliness and social signals) are all used in feature generation below.

Returning to FIG. 3, execution then proceeds to steps 312 and 316 simultaneously. Specifically, the URL summarization documents are indexed at step 314 and stored in index database 222. At the same time, the URL summarization documents are stored in URL summarization database 220 at step 316. Then, execution proceeds to step 318 wherein URL data is retrieved from the summarization documents stored in database 220. At this point, RSS feeds are discovered and collected as follows.

Execution then proceeds to step 320 wherein the RSS feeds are extracted from the metal data within the URL summarization documents. Next, at step 322 the user data for each RSS feed is aggregated as follows:

-   -   RSS=({user}, {actor}, {action}, {author}, {publisher}, {# of         URLs})         where the user is the author of post, the actor is a person that         engaged, action is the user action (e.g., like, favorite,         tweeted, comments, share), author is the author of the post,         publisher is site where URL was published, and # of URLs is the         number of URLs.

Execution then proceeds step 324 wherein the social importance score of each RSS feed is computed as a function of a Klout score and aggregated data. This computation is similar to the URL scoring above except that now additional information from the URL summarization document is used. The social importance score (F^(RSS) (rss) is computed as follows:

${F^{RSS}({rss})} = {\sum\limits_{{{i\;\prime}❘{t \in T}},{d^{url}.{rss}}}\;{{w(e)}*\left( {{\alpha*{g\left( k^{u} \right)}} + {\beta*{g\left( k^{a} \right)}} + {\gamma*{g\left( k^{d^{url}.p} \right)}} + {\delta*{g\left( k^{d^{url}.c} \right)}}} \right)}}$ where the parameters identified above are defined as follows:

-   -   Interaction tuple with document summarization: i′=(t, url, u,         k^(u), a, k^(a), e, d^(url))     -   URL document summarization: d^(url)=(rss, p, k^(p), c, k^(c)).     -   rss: RSS source extracted from HTML metadata of URL. This is an         RSS in which a URL occurs.     -   p: publisher/site where URL was published (e.g., @cnn for         cnn.com).     -   k^(p): Klout information of the publisher.     -   c: creator/author of the URL (e.g., @TimListerCNN journalist         that authored an article on cnn.com).     -   k^(c): Klout information of the creator/author.     -   T=[t_(start), t_(end)]: Time window in which we score given url.     -   α: original user importance weight (scalar).     -   β: actor importance weight (scalar).     -   w: event weighting function to allow us to weight different         events differently (Twitter comment vs. Facebook comment etc.).     -   g: user weighting function. Given users info, and in particular         Klout info derive weight of given user.     -   γ: publisher/site importance weight (scalar).     -   β: creator/author importance weight.

An example of one possible simplified formula can be the following:

${F^{RSS}({rss})} = {\sum\limits_{{{i\;\prime}❘{t \in T}},{d^{url}.{rss}}}\left( {{0.1*{k^{a}.{score}}} + {0.2*{k^{u}.{score}}} + {0.3*{k^{d^{url}.p}.{score}}} + {0.4*{k^{d^{url}.c}.{score}}}} \right)}$ where k·score is the Klout score for the user. Similar to the URL scoring function above, a Klout score may be replaced with another weight value (e.g., 1, where all users have the same influence) as known to those skilled in the art.

Execution then proceeds to step 326 wherein the RSS feeds are ranked by the social importance scores. Execution then proceeds to step 328 wherein the actual URL inside the RSS feeds are fetched (collected). Execution then proceeds to steps 330 and 312 wherein a summarization document for each URL within the RSS feeds is generated (stored) and indexed at step 314. The summarization documents are also stored in index database 222.

FIG. 4 depicts example method steps for implementing the feature generation, model selection and serving modules shown in FIG. 2.

In particular, execution begins step 400 wherein optimization engagement criteria is selected based on a user input data 402. That is, it is the collected data that has been previously inputted by the user. The user input data the location where the user resides, age, user selected topics, etc.

Execution then moves to step 404 wherein a pre-created model (discussed below) is selected based on the engagement criteria. The model criteria is defined by the type of interaction (e.g., like, click, shares, views etc.). In this respect, scoring of the URL summarization documents may change depending on the model selected. That is, the framework for model creation and selection is independent from data collection and URL scoring (described below).

Once the particular model is selected, execution proceeds to step 406 wherein (complex) query documents are generated about the user (e.g., user information, current timestamp). The query document, in addition to topic(s) that a user initiated requested, captures any additional information with respect to the user, which can be used to create better personalization experience. In this context, personalization refers to optimization per criteria selected with respect to the user. For example, if @Nike accesses the topical page on “Big Data,” knowing that @Nike's audience is interested in “Running,” and “Health,” articles might be prioritized that are about “Big Data” but related to “Running” and “Health.” The query document will identify the user (i.e., party of interest in FIG. 7), the user's topics' frequencies (selected, interest, expertise, and audience interest/expertise), user's keyword frequencies and other information such as age, user's location, Klout score of the user etc. A query document appears in FIG. 7 depicting these identifications. A specific example query document appears in the rear of this disclosure.

Execution proceeds to step 408 wherein the summarization documents stored in the index are filtered based on known topical data and derived properties relating to the user. The derived properties will include the relevant scoring described above with respect to creating URL summarization documents. For example, if the user is Nike (representative), the data already collected and known about the company may include sports information relating to running, football and other sports. The index typically includes over 1 million URL summarization documents. Initial filtering is performed to reduce that amount to a reasonable number. In practice, 50,000 URL summarization documents are considered manageable but those skilled in the art know that any number of URL summarization documents may result from the filtering process as desired.

Execution proceeds to step 410 wherein features are generated for each query document and summarization document. Reference is made to FIG. 7 wherein an example block diagram is depicted illustrating how the features are created. Each feature (F (Q,D)) described below) is created as a function of the data in a URL summarization document and Query document for that user. In particular, several cosine similarity calculations are performed on the vector data (e.g. weighted topic, and keywords) in a URL summarization document and the data in the query document to generate some of features contributing to feature vectors. For relevance ranking, each query if matched against filtered documents to create a unique query, the query document feature vector, is shown below:

-   -   Q₁: F (Q₁,D₁), F₂ (Q₁,D₂) . . .     -   Q₂: F (Q₂,D₁), F₂ (Q₂,D₂) . . .         where Q is identified as data from the query document and D is         identified as data from the URL summarization document. For         example, the cosine query-URL topic Interest similarity is         between the vector of data variables in the URL summarization         document and the vector of data variables of the query document.         This will measure the similarities between the two vectors.         Similar calculations are conducted for cosine query-URL topic         expertise similarity, cosine query-URL text interest similarity,         cosine query-URL text expertise similarity, cosine inquirer-URL         text audience interest similarity, cosine inquirer-URL text         audience expertise similarity, cosine inquirer-URL metadata text         interest similarity, cosine inquirer-URL text expertise         similarity. Some of the features are only based on the URL         summarization document alone as the ones discussed above in         relevant scoring. Some of these features include: topical decay,         social relevance, timeliness, etc. The resulting features amount         to about 50.

Execution proceeds to step 412 wherein the selected model is applied to calculate scores (rank values) for each URL summarization document. The model is used to incorporate the importance of a feature (and calculate a score based on the importance of the model). The specific weights are determined by the model selected. In practice, the weights are applied to feature vector parameters and are then summed per summarization document to obtain a score as follows:

-   -   S (Q,D)=M*F (Q,D) (i.e., linear form S=M(D))         where M is the model selected, F is the feature vector based on         query document Q and URL summarization document D. For example,         of a linear model, if F and M are as follows:     -   F (Q,D)=[‘TEXT: 0.5, ‘RECENCY: 0.9]     -   M=[‘TEXT’: 1.0; ‘RECENCY: 10.0, ‘SPAM’: −100.0], then     -   S=M*F (Q,D)=0.5*1.0+0.9*10.0+0*(−100.0)=9.5         So, the score in the example above is 9.5 for a given model M         and feature vector F.

Execution proceeds to steps 414 and 416 wherein the URL summarization documents are sorted by score and the top (T) number of URL summarization documents are presented to the user. The URL summarization documents are ranked in order by score. T is set to 15, but those skilled in the art know that any number of URLs may be presented to the user.

As described above, the specific weights are determined by the model selected. FIG. 8 depicts an example method steps for implementing how models are created. Execution begins at step 800 wherein a user will access the Klout.com website (Klout.com). For example, the user could be corporate representative (e.g., Nike), government representative, an independent person or any other person as described above. At this point, the user requests a query for relevant URLs for topics at step 802. A query document is created as described above by the request. The execution proceeds to step 804 wherein the user will receive the results using content discovery platform 200 described above. The results will include a list of URLs ranked in order of score as described above.

Execution proceeds to step 806 wherein user interactions are received. These interactions include social network user reactions such likes, clicks, shares and views of a URL. At step 808, these other users' data is stored in user interaction log database 226 in the format as follows:

-   -   {Q, D, I}         where Q is the user query document triggered by the user         request, D is the URL summarization document described above and         I is the interaction is the reaction type captured as         represented in the following examples:     -   Example 1 I={click: [D₁, D₂, D₃], share: [D₁]}     -   Example 2 I={share: [D₁₀]}         The data is stored to enable the user (requesting the query) to         search the database for specific information as desired.

Execution then proceeds to step 810 wherein social media data from social networks 104 is retrieved from social network media database 224 (that was collected by collectors from database 214). The social media data includes a user's postings, and other user's interactions etc.

Execution then proceeds to step 812 wherein the interaction data and social network data are combined as follows:

-   -   Combined data={Q, D, I, optionally SE}         where SE is a social engagement optionally retrieved outside of         Klout.com (social media data) and Q, D and I are as identified         above.

Execution proceeds to step 814 wherein the resulting train data is generated based on the combined data. That is, a label set is created at sub-step 814 a and the model is built at sub-step 814 b. The label is created for each feature vector. Each unique pair (Q,D) within label set has unique label L_((Q,D)) assigned for it. This is represented as a label feature vector tuple:

-   -   (L_((Q,D)),F (Q, D))         where L is the label set assigned for a feature for the         following optimization criteria:     -   {L₁: clicks}     -   {L₂: shares}     -   {L₃: views}     -   {L₃: social network engagements outside of Klout}         where the social network engagements are retrieved from a         Klout.com account of the user. L₃ is an optimization for the         audience (of user engagements/interactions), not of the user         requesting a query. For example, L_(3 (Q,D)), captures how many         social network (re-tweets, favors, Facebook likes) interactions         in total occurred when @Nike shared a URL whose summarized form         is D.

Execution then proceeds to step 814 wherein a model is built to fit the label set. It is the weight of the label sets that are used for calculating scores for the URLs as described in FIG. 4. There is a weight for each feature within feature vector. Different label sets refer to different optimization criteria. Machine learning is used to generate desired engagement outcome. Different optimization criteria are designed for different cohort of users. For example, a cohort may be broken down into three categories: the casual user (e.g., those that click only); mid-level users (e.g., those that share articles); and large audience (big brands desire a large audience engagements). Each cohort will likely use a different model. The models built are stored in model database 218 for subsequent use by content discovery platform 200.

For a given user, different topical source sets of topics are kept that relate to the user in different ways (some sets are expertise, interested—based on user behavior, user audience interest or topics that the user simply marked as interested.). Either a user (e.g., Nike) or administrator of content discovery platform 200 may select the cohort through a cohort controller. Based on the cohort, a model controller will determine the model to be applied. The administrator can experiment to see how different models perform and create new models based on outcomes. Data is served to a user by model ID (identification) and the user's actions are logged together with the model ID so that later, based on the user's actions, different metrics may be derived to measure different metrics (model performance).

It is noted the embodiment of in this disclosure incorporate several the software modules and several steps to implement the software modules. However, those skilled in the art know that additional or lesser number of software modules or steps may be employed or the order of steps may be altered to achieve desired results. In addition, the databases disclosed may be any data store (storage) as known to those skilled in the art know may be used to achieved desired results.
